hey all, this will be my first post, and i'm just wondering is there any other manufacturer that produce aftermarket coil for TR's. so far i could only find bosch and genuine parts only. i was thinking to get some sort of hipo coil or something. any idea...?

First of all:

Welcome to the club! :) Nice to see another TR amongst the ranks!

Aftermarket coils, the only ones I know of are by Haltech, but they're a direct fire setup.

Nothing wrong with bosch. Im assuming you want a stronger coil? You'd also have to upgrade your distributor to ensure that extra spark isnt wasted. I cant remember what company makes them..but I did read a while ago about upgraded dizzys...sorry I cant help you.
